Abstract
The invention discloses a vertebral body support for a vertebral body bone cement implanting operation. The vertebral body support comprises a support and a tectorial membrane or fabric coated outside the support; one end of the support is an opened, and the other end of the support is closed; and a plurality of small holes are formed on the tectorial membrane or the fabric at the side wall of the support. The vertebral body support is simple in structure, is capable of preventing the bone cement from leaking in large quantity, and is capable of avoiding surgical risk.
Description
Technical field
The present invention relates to a kind of centrum support for the implant surgery of vertebral bone cement, belong to medical instruments field.
Background technology
At present, in vertebral body operation, adopt the open circuit instrument to set up passage, after the vertebral body position expansion of sacculus with fracture, inject bone cement, bone cement can be along the vertebral bone gap leakage, and the heat that produces when bone cement solidifies its hetero-organization of vertebral body of might burning is such as nervus centralis, cause some postoperative complications, in addition, single bone cement, intensity is also not too high.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, provide a kind of simple in structure, can prevent that bone cement from leaking, avoiding the centrum support that is used for the implant surgery of vertebral bone cement of operation risk.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of centrum support for the implant surgery of vertebral bone cement, comprise support and the overlay film or the fabric that are coated on the support outside, one end of described support is the opening shape, the other end of support is closed, and has some apertures in the part that is positioned on the rack side wall on overlay film or the fabric.
Further, described support is network structure, and forms or adopt the metal tube cut to form or injection molded by macromolecular material by metal wire knitted.
Further, described tinsel is nitinol alloy wire or stainless steel silk or titanium silk.
Further, described metal tube is made by cochrome or Nitinol or rustless steel.
Further, described macromolecular material be meet biocompatibility requirement absorb or the macromolecular material of nonabsorable is made.
Further, described support is the U-shaped structure of upper end open, lower end closed.
Further, described support is the ball shape structure of upper end open, lower end closed.
After having adopted technique scheme, the present invention has following beneficial effect:
When 1, using, the bone cement main body is wrapped in internal stent, can prevent that bone cement from leaking in a large number, owing to be enclosed type near nervus centralis one side, bone cement can not be revealed, and has stopped a large amount of risks of revealing its hetero-organization of burning of bone cement.
2, the support that uses is equivalent to add bar-mat reinforcement one in bone cement, and the bone cement after solidifying is similar to reinforced concrete structure, and the intensity of bone cement increases greatly.
3, the sidewall of support, except on the outside upper overlay film of bottom lock end or the fabric with aperture, bone cement can ooze out through aperture on a small quantity, produces with the diaphysis of periphery to be connected, bone cement and vertebral body can be carried out good fixing.
4, adopt cancellated support, good plasticity and adaptivity are arranged, its shape can be carried out corresponding deformation with the size in vertebral body hole after the expansion, and contoured cradle can change, radially or longitudinal length all can produce according to the size of vertebral body corresponding the variation.
5, the support with developing ring has good development under X-ray, can clearly show the position of rack far end and near-end, greatly makes things convenient for the doctor to control the injection rate of bone cement.
